Destiny, cause and effect, sin and punishment are always cruel and terrifying. Liu Zeren, thirty-nine years old, traffic police officer, is dedicated to his duties, but he is by no means a heroic detective in the hearts of others. He is known as "dumb fire", unloading his shoulders, copying cards, and the driver calls him "Death". When he meets him, he will be copied. When it was seventeen years, there was no big mistake, and of course no credit was made. But the Liuze people win in the world. Half a year ago, he accidentally broke a road kidnapping case and escaped a higher level of recognition. Three months later, he decided to divorce his wife, Xu Meihua, in order to be with the newly-acquainted 23-year-old woman, Yu Anna. Since then, the people around him have been unfortunate, and their ex-wife, father-in-law, robes, cleaning women, delivery boys, delivery truck drivers, etc., have suffered bad luck. Traffic police officers have always been one of the dangerous professions, but the accidents have occurred again and again, and again in the multiples of seven, in the Liuze people. Liu Ze people left heaven on one foot and one foot went to hell until they were tortured to the forty-ninth day. Happiness is ruined and the cruel life is restored. He wants to retaliate against those who have been manipulating his life.
